Abstract
Yokohama Raw Silk Inspection warehouses, completed in 1926 to keep all raw silks which had gathered to Yokohama. This summary reports on some observations identified during the dismantling. The followings were turned out; the ways of creation and installation, and the designs.
The way of creation of RC canopy beam was also identified. Wood piles were used for improvement of the foundation. The joint parts of reinforced bars welded together were found from the basement. Moreover, the survey shows that warehouse D had a high quality of the way of welding compared to that of warehouse B; as for warehouse B, the parts were joined together with electric power, so-called flash-butt welding. As for warehouse D, the parts were joined together with electric power and compression, so-called upset-butt welding.
